Join King County project managers to hear about upcoming projects that will use large wood in rivers and streams to reduce flood risks and improve habitat. King County uses large wood to redirect river currents and prevent erosion in levee repair and flood risk-reduction projects, many of which are funded by the King County Flood Control District. The County also uses large wood to improve habitat for fish and wildlife.
Meeting presentations will include descriptions, schedules and anticipated impacts of several projects that are in the planning stage and include using large wood in rivers. Among the projects to be discussed:
- Cedar River basin: Herzman Levee Setback and Trail Stabilization, Riverbend Levee Setback and Floodplain Reconnection and Jan Road Levee Setback;
- Snoqualmie River basin: Upper Snoqualmie River Mitigation Wood Placement, Haffner-Barfuse Levee Setback, plus several smaller levee repair and maintenance projects; and
- Green River basin: Lones Levee Setback, Chinook Wind Mitigation, and Lower Newaukum Creek.
